Abstract
A backless electrical box is formed out of a single piece of material, with a front and sides of the box being parts of the same single piece of material. The front of the box has an integrally-formed mud ring that extends forward from a front base of the front. The sides are made out of material bent back from two opposite edges of the front base, bent around to form the four sides. Some or all of the sides may have seams in them, which may be secured by portions of material overlapping along some or all of the height of the sides, riveted or otherwise attached together. Mounting flanges may extend from the other two opposite edges of the front base. Tabs bent downward from the mounting flanges may be used to cover holes in the sides that extend rearward from these two other opposite edges.
